Abstract: Systems and methods are described herein to use a discharge pressure of a compressor to drive refrigerant in a refrigeration system. Particularly, systems and methods are described herein to help recover liquid refrigerant from a liquid refrigerant section and/or a condenser coil to be used in a heating/defrost mode in a transport refrigerant unit (TRU). The liquid refrigerant can be recovered by directing the discharge refrigerant of the compressor to a liquid refrigerant section, which may include a receiver tank, a dryer and associated refrigerant lines, and/or a condenser coil. The discharge pressure of the discharge port can help drive refrigerant trapped in the liquid refrigerant section and/or the condenser coil into the heating/defrost branch of the TRU, which may include an evaporator coil, an accumulator tank and/or associated refrigerant lines.

Abstract: An electronic transceiver module and method for controlling the electronic transceiver module for network wireless communication in electric and/or electronic devices or systems in high frequency bands up to 10 GHz, including a device for wireless communication connected to an antenna entry, a control device, and a memory device. The control device is connected to the memory device, to the device for wireless communication and to a comparator block, which is further connected to the memory device. The memory device includes at least two separate memories for storing information identifying various wireless networks.

Abstract: A module for wireless communication between electric or electronic equipment or systems, in high frequency bands at least in the range of 300 MHz to 2.60 GHz, particularly for home and office automation systems, comprising a block (RF) for wireless communication, connected to an antenna interface (ANT) and a power supply interface (Uin) and also to a control block (RFCON). The module further contains a control unit (MCU) comprising a central processor unit (CPU), a memory (MOS) with the operational system control code to ensure the function of wireless communication and a memory (MAP) for storing or starting up a user-defined applicational control code, where the control unit (MCU) is connected to the control block (RFCON), to the communication interface (COM) of the module and to the power supply interface (Uin).

Abstract: A method for controlling an electric motor for an automobile wiper system includes a calibration curve in which data is converted into the angular value of the position of an output shaft and a correction is made depending upon a direction and magnitude of deviations. The electric motor has a stator with a lid with permanent magnets and the output shaft has a worm wheel with pole extensions of permanent magnets and a sensor of the angular position of the output shaft.
